A678 grade A plates API standard 650 open-top tanks

Design calculations and drawings required API standard 650 open-top tanks for the fabrication and erection of each API 650 tank. A drawing index for each API 650 tank is required and shall be re-submitted each time drawings are revised and re-issued.

The company's logistics team adheres to the development concept of “gathering advantages, providing superior services, creating value, and leading the market”, and tightly focuses on the strategic positioning of “developing large-scale steel logistics and building large-scale steel supermarkets”. Facing the whole country and integrating into the world to build an "one center, one network" international circulation system. Through the development of 5-10 years, it is expected to form a modern steel industry with annual operating income exceeding 2.5 billion yuan.

Combination of Design Loads
The inner tank API standard 650 open-top tanks shall be designed for the most critical combinations of loading that result from internal pressure and liquid head, the static insulation pressure, the insulation pressure as the inner tank expands after an in-service period, and the purging or operating pressure of the space between the inner and outer tank shells, unless the pressure is equalized on both sides of the inner tank.

Large-scale vertical API standard 650 open-top tanks mostly use internal tank bottom heating coils to heat the medium stored in the storage tanks. The heating coils are mostly smooth tube structures arranged in an annular circle along the bottom of the API standard 650 open-top tanks. Commonly used heating methods include hot oil circulation heating method and hot water steam circulation heating method. The hot oil circulation heating method is to continuously extract part of the liquid medium from the storage tank, and then return it to the container to mix with the medium in the tank after heating, and the heat is quickly transferred through mechanical stirring.
